DEVICE FOR PROPELLING BOATS.

SPECIFICATION forming part of Letters Patent-No. 453,704, dated June 9,1891.

Application filed January 19, 1891. Serial No. 378,250. (N0 model.)

To all La7/1,0772, it may concern:

Be it known that I, BENJAMIN B. PEAsE, of Castle Creek, in the county ofBroome, in the State of New York, have invented new and usefulImprovements in Devices for Propelling Boats, of which the following,taken inv connection with the accompanying drawings, is a full, clear,and exact description.

My invention relates to the propulsion of boats and mechanisms therefor.

My object is to provide improved crankdriven independently-operatingside wheels mounted on separate shafts, being mounted in bearingsmounted upon a frame detachably secured within the boat and providedwith side extensions arching upward over and projecting beyond thegunwale.

My invention consists in the several novel features of construction andoperation hereinafter described, and which are specically set forth inthe claims hereunto annexed.

Itis constructed as follows, reference being had to the accompanyingdrawings, in which- Figure 1 is an isometrica-l elevation of a boat withmy propelling mechanism in position. Fig. 2 is a top plan of thepropelling mechanism detached. Fig. 3 is a sectional elevation of theboat and frame carrying the wheels, the shafts and cranks being omitted.

A is the boat, and 1 1 are risers or horizontal cleats, secured withinit on opposite sides between the gunwale and keel.

B is a rectangular frame, supported upon these risers and detachablysecured in place by means of the bolts 2, which engage with them, andthe hand screw-nuts 3 upon said bolts. Upon the opposite sides of theframe I secure the outriggers, each of which comprises a base 5, avertical post G, bent at the top to form the flange 7, said upper endand flange being adapted to form part of the journal or bearing S, and 9is an arm arching upward and outward in close proximity to the gunwaleand projecting beyond the gunwale like an Outrigger, and adapted to forma part of a journal or bearing 10 on top of its outer end. Braces 1l,connecting this arm at its outer end to the frame, serve to' steady theOutrigger against lateral vibration.

C C- are the paddle-wheels, each secured upon the outer end of a shaft12, which is journaled in the bearings S and 10, and each shaft isprovided upon its inner end with a crank-arm and handle 13. The sidebars la of the frame B serve as seats for the operators.

It will be seen that the wheels can be operated together though mountedin separate bearings, or separately, both in the same direction or inopposite directions. It will be further seen that the weight of vthewheels does not bear upon the gunwales to spring them and rack the boat,and also that all of the lateral strain is borne by the frame andthrough that by the body of the boat, its planking and ribs, and theseare strongly reenforced by the stron g risers and the length of theirbearing upon them.

By loosening the hand-nuts the whole frame and wheels can be removedfrom the boat.

That I claim as my invention, and desire to secure by Letters Patent,is-

1. A boat-propeller comprising aframe supported by risers within theboat and detachably secured thereto, outriggers secured to the frame andarching over and projecting beyond the gunwale on both sides of theboat, a j ournal-bearing upon the outer end of each Outrigger, a posterected upon the inner end of each Outrigger, a journal-bearing uponeach post, a shaft j ournaled in the bearings on each side of the boat,cranks upon the inner ends of the shafts, and paddle-wheels upon theouter ends of the shafts, in combination, as set' forth.

2. A boat-propeller comprising a frame supported by risers within theboat and detachably secured thereto, outriggers secured to the frame andarching over and projecting beyond the guuwales 0n both sides of theboat, a journal-bearing upon the outer end of each Outrigger, a posterected upon the inner end of each Outrigger, a journal-bearing uponeach post, a shaft j ournaled in the bearings on each side of the boat,cranks upon the inner ends of the shafts, paddle-Wheels upon cured tothe outriggers and to the frame on the outer ends 'of the shafts, andside braces each side, as set forth. zo secured to the outer ends of theoutriggers In Witness whereof I have hereunto set my and to the frame,in combination, as set fort-h. hand on this 13th day of January, 1891.
